Phaedrus (/ˈfiːdrəs, ˈfɛdrəs/; Ancient Greek: Φαῖδρος; 138 – 70/69 BC[1]) was an Epicurean philosopher.
Phaedrus was at that time an old man, and was already a leading figure of the Epicurean school.
[3] He was also on terms of friendship with Velleius, whom Cicero introduces as the defender of the Epicurean tenets in the De Natura Deorum,[4] and especially with Atticus.
Cicero wrote to Atticus requesting Phaedrus' essay On gods (Greek: Περὶ θεῶν).
[6] Cicero used this work to aid his composition of the first book of the De Natura Deorum.
